New RSR54 Solid State Relays – High Performance and Efficient Heat Dissipation
New RSR54 Solid State Relays – High Performance and Efficient Heat Dissipation
Our company is expanding its range of solid state relays with the new RSR54 series – single-phase solid state relays with a high current range from 25 A up to 125 A. They are available in various voltage configurations (24…280 V AC, 24…530 V AC, 24…660 V AC) and with either AC or DC control.
RSR54 combines a compact design with high reliability and excellent overload resistance.
Zero-cross switching and a thyristor (SCR)-based output ensure spark-free operation and exceptional device durability.
Efficient heat dissipation with dedicated heatsinks
The new RSR54 solid state relays are designed to effectively handle thermal management. A variety of RH-series heatsinks are available (such as RH08, RH08-F, RH16, RH21), helping to maintain optimal operating temperatures even under high current loads and elevated ambient conditions. For instance, the RH08-F heatsink with fan features a very low thermal resistance of 0.35 °C/W, providing effective cooling even in demanding applications.
Technical specifications of RSR54 relays:
- Load current: 25 A, 40 A, 60 A, 80 A, 100 A, 125 A
- Control voltage: 3…32 V DC or 90…280 V AC
- Zero-cross switching
- Optoisolation: 4,000 Vrms
- TVS protection (Transient Voltage Suppression)
- LED status indicator
- Screw terminals: M3 (input), M4 (output)
- Mounting: panel or heatsink
Typical applications of RSR54
RSR54 relays are ideal for industrial environments where maintenance-free, durable and silent operation of actuators is essential, including:
- Temperature chambers
- Food and plastics industry
- Heating systems and resistive heaters
- Processing machinery
RSR54 – reliability, performance, and thermal safety in one relay.
